IMPROVEMENT IN TuRsin E WATER-WH EELS.

Specification forming part of Letters Patent No. 201,635, dated March26, 1878 application filed February 5, 1878.

To all whom "it may concern:

Be it known that I, ISAAC SHERoK, of Fremont, in the county of Sanduskyand State of Ohio, have invented certain new and useful Improvements inTurbine Water-Wheels; and I do hereby declare the following to be afull, clear, and exact description of the invention,

which it pertains to make and use it, reference being had to theaccompanying drawin gs, which form part of this specification.

My invention relates to turbine water-wheels, and especially to thevalves or gates that govern and control the admission of water to thewings or buckets.

It consists in any suitable mechanism whereby said valves or gates aresimultaneously operated by a device having two or more points ofattachment upon the rim, body, or periphery of said gates or valves, aswill hereinafter more fully appear. a

In the drawings, Figure 1 represents aplan view of a device constructedaccording to my invention; Fig. 2, a view of the same incrosssection,taken through the two arms operating the valves or gates;Fig. 3, a detached View, showing the annular gate, with its attachedarms moving and controlling it from more than one point of contact.

It will be observed that the gates are here opened and closed by a ringor annular piece, A, having openings A made therein, corresponding innumber, size, and shape to the peculiar necessities of the wheel underconstruction. Upon these features I do not limit equally applicable towheels of a large variety of description.

Heretofore it has been customary to move the annular valve A from asingle point of attachment, and this has resulted in difficulty ofturning said valve, owing to the unequal strain brought thus upon it.The pull being only at one point, the result is more or less binding andfriction, and consequent difficulty of manipulation.

My invention has for its principal object the obviation of thisdifficulty, by having more than one point of attachment upon the annularvalve A for the power operating to turn it.

My preferred construction is substantially such as shown in thedrawings, where this power is applied at two diametrically-oppositepoints upon the body of the ring A, thus always securing a balance andequality of pressure or pull upon said ring or valve, and effectuallypreventing any binding or objectionable friction.

It is obvious that my invention might be so modified that, instead ofthe two opposite points of attachment for the power turning thevalve-ring A, there might be three, four, or more such points ofattachment. Two, however, serve a good purpose, and this construction Irecommend as the most economical. The arms A may be simultaneouslyoperated in any suitable way. The manner here shown is to attach them toa geared collar, B, surrounding and turning upon the column B. Thegeared collar meshes with a pinion, O, jonrnaled and attached to thedeck of the wheel, and provided with a shaft, '0, which may be turnedwith a crank hand-wheel or key, thus revolving the pinion G and collarB, to which the arms A are attached, and thereby operating the annularvalve-ring A.

In the deck of the wheel are made slots D, through which pass the arms Aor parts attached thereto, for connection with the valve ring A. Ifthese slots D were left open and unprotected, water would pass throughthem, and work deleteriously to the operation of the wheel. I thereforeprovide the shields or covers D, which may be attached to or made a partof the arms A These are so constructed as best to prevent the entranceof water through the slots D.

What I claim is- 1. A turbine water-wheel the valve-ring of which hastwo or more pointsof attachment for the power that moves it to open orclose the ports admitting water to said wheel, substantially'as and forthe purpose specified.

2. The valve-ring A, in combination with two or more arms, A ,ortheirequivalent, substantially as and for the purpose shown.

3. The combination, with the deck of a turbine water-wheel provided witha slot in which the angular extremity of the valve-ring arm hasmovement, of the shield formed on said ring A, substantially as and forthe purpose shown.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

ISAAC SHEROK.
